WARP BEAM Filed Aug. 20, 1928 Patented May 13, 1930 UNITED STATES .TABEZ WTLxTNsoN, or FALL RIVER, MAssAcrrusETTs WARP `Bizarr' Application Vle. August 20, 17928. Serial No. 300,825.

My invention relates to an improved warp beam and more particularly to a positive locking device for locking together the head and barrel portions of the warp beam to prevent relative rotation. When used on a high speed warper, such as a Barberolman warper, there is a tendency to relative rotation betweenthe barrel and the head when the rapidly rotating beam is brought to a quick stop. This relative rotation is undesirable when there is a break in the yarn as it permits several yards ofpyarn to run of the creel before the broken yarn may be ixed.

It is an object of my invention to provide a simple, positive lockingdevice for a warp# er beam head which is simple in structure, reliable in operation and economical of manufacture. y

Another objectof my invention isto provide a positive locking device for use on' a warp beam which Vdispenses with the need of internal fastenings or screws `or bolts-on the inside of the barrel of the warp beam which sometimes work loose and wreck the beam. i

VA further object of my invention is to provide a warp beam head which is light and yet suiiiciently strong to withstand the centrifugal force induced by rotation at very high speed. Y

Still another object of my invention is to provide a locking device for a. warper beam which comprises lug portionson the head members which t within notch portions on the extremities of the barrel member, the lug portions and the notch portions being so distanced from the axle as to effectively resist the tendency to relative rotation and simultaneously resist the tendency to break. Other objects and advantages will appear from the following description taken in .con-

`nection with thel accompanying drawing.

I attain these objects and advantages by means of the constructions shown in the accompanying i drawing, wherein Figure l is a sectional view of the end of a warp beam showing the locking means on the head Amember fitting into the notcheson the end of tliebarrel member. There isa further the inner Figure l5 is an enlarged View of a disk member for attachment to a head member having peripheral lugs for insertion into the notches on the barrel member and having cored bosses lfor the insertion of tie bolts for securing the same to the head member.

Figure 6 is a cross sectional view of the disk member shown in Figure 5.

Figure 7 is a side elevational view of the disk member shownin Figure 5 showing the side reverse to that in Figure 5.

Similar numerals refer to similar parts t throughout the several views of the drawing. I

Referring to Figure l of the drawing, l denotes a head member, 2 the barrel member of a warp beam, av shaft or `gudgeon 3 passes through the center of the head member and through the axial center of the barrel member 2. `Mounted on the shaft 3 is the wooden center 4, being secured in place by a split nut 5 whichprovides a bearing surface forthe wooden center against the shaft 3. Lag screws V6 Vare provided for positioning the wooden center. Each extremity of the barrel portion is provided with notches 7 (see Figure 4) which serve a purpose to be stated hereinafter. The head 'member shown, is a large disk of laminated wood secured together kby a rim and is a well known construction, however, it is to be understood that any other type of wheel ymay beused and that the invention is equally applicable u to wooden or metal beam heads.

Secured to the headv member 1 by thebolts 8 and concentric therewith, is a disk member 9. The disk member, as shown in Figure 2, is ixedly secured to the head member by ..ing'thereinwwhichiis -adaptedztoj circumscribe the exterior of thefnutgandtherebyfpievent `.itsfturning. .Thisfstraprmember isplaoed on #the head memberafter-the nut'vis: screwedY on f eter as to be insertible into the counterborel 21 of the barrel@ memberaridito .fitvsnugly therein. The head member is held in fixed engagement with the barrel member by means of the axle nutll. In order topre- `vent the Working loose ofthe axle nutV 11, a blocking; .device 12is provided. Asfzshownfin l*`igu'1e-..3,4 this-locking :device: consists of 1 a strap member which has a hexagonalxopenf. its maximum distance. .The --opening fin'fthe strap member may be varied lto fit the -contour ofthe nut. It Iis apparentf'thatsino'rder to remove the; nut ,itfisnecessary. v'tozlirstfre move the locking strap. "This isl ofi great imf portance in order` :tog prevent ther Working .loose of the head and barrel members.

ReferringxtQFigures 5 and6', there y-is'there Vshown a-metalidisk member 15 which serves .-thesame purpose as the-disk 9. a'bve'referred to. Thedisk 15 is provided-With'cored-bosses p 16,'-fthe-fl2angef17f-andperipheral lugs: i8. In
